SSN's are NOT unique numbers.
One of the reasons that credit companies sometimes will not tell you who is using your SSN is that it might just be a mistake on the name.
They are supposed to be unique, there have been very few duplicate numbers issued to two different individuals. So, sorry, your statement that they are not unique is mostly false. Also, none have been reissued once the original holder died. It will take several decades to exhaust the unused areas of the number sequence that remain.
Would you be willing to use SSN's as the primary key in a database table?
A number that you don't control.
Honestly?
